Creating user-defined type (UDT) schema

Creating user-defined type (UDT) schema.

User-defined types (UDTs) are a method of defining non-standard data types for use in both Cassandra and DataStax Graph
(DSG). UDTs can be created with either CQL or Gremlin for use in vertex or edge
label schema for graphs. UDTs can be creatd with all data types, as well as other
UDTs. They are a useful way to construct groupings of properties that are
associated. UDT schema have three operations:

create a UDT with create()

describe a UDT with describe()

drop a UDT with drop()

Prior existence of a UDT can be checked using ifNotExists()
before creating a UDT.
